Has anyone ever tried this?

Would be very cool if it works!

Funny you should ask as I just threw out the romaine I was trying to grow. It did not work for me at all. Maybe I was doing something wrong....I have had really good luck with regrowing green onions this way.

I do this with the lettuce I grow myself, but never tried regrowing supermarket lettuce. If its sitting in just water while it grows roots, the new leaves aren't going to have any nutrition value, so I don't see the point.

When I grow my own lettuce, I just cut off the outer leaves and let the inside of the plant continue to produce more.

Yes, for green onions it works well - but do change the water often or it gets slimy. Last summer I repeatedly rooted green onions and then put them in the garden. When you grow something like this in water, it is getting nutrients only from what is stored in the bulb.

I tried it with celery as well. It did root, but then it grew very very very slowly in the garden. Nothing to harvest by the end of the summer.

I will try it with Romaine in the gardening season, which begins fairly early for lettuce. Still, i think it will need to be planted in the soil to get the nutrients it needs to grow --- unless you use some sort of hydroponic fertilizer to add to the water.

Have done it successfully with onions, green onions, celery, but not lettuce.
Like herbgeek, I use the cut-and-come-again method with my lettuces.
